My mother has been staying alone since a very long time, around 9years and has had a very upsetting and tortured married life. She has gradually developed the following symptoms: forgets things very quickly like if i have told her about something she will ask me same thing again in half hour. Or might forget an entire plan made today for tomorrow. Secondly she gets very confused managing household chores too. Thirdly she always talks roughly if any situation is against her. She always wants to prove that whatever she is thinking is right and everyone else is wrong. If we try to make her know the mistake she made, she wont accept and gets very angry and talks about all the negative things. I am very worried if she has any serious medical conditions like Alzheimer's or something. She refuses to show to any doctor and always says that i am fine but you all are making me crazy.
